Data access
Data access is free and open
Aletheia Analytics operates the reference deployment of the Gavel Protocol and publishes the Bitcoin yield curve as a public benchmark. The full API — auction data, protocol state, current indicator values and the canonical curve — is available without a key and without charge.This is one venue's data. Measurement across the Bitcoin-collateralised credit markets moved to The Bitcoin Credit Stack on 30 August 2026, on the same terms: no key, no charge.
Free, no key, no signup
The Bitcoin yield curve
Current market-discovered fit and the raw fitted points.
Protocol state & auctions
Every auction, bid and loan, read directly from the chain.
Current assessment values
Credit surface, TCI and implied price - the assessments derived from this venue’s own book.
Interactive & rendered views
The dashboard, sparklines and the yield-curve visualisations.
Commercial data products will follow when the market has the depth to make them meaningful. We will say so here. Aletheia Analytics participates on its own account to seed observable auction data; until external participation dominates, the curve is presented as a data product rather than marketed as an independent market assessment.
